SPECIFCATION forming part of Letters Patent No. 601,594, dated March QQflBQB.

Application filed June 22,

To a/ZZ whom it may concern:

15e it `known that we, J OSEPII SIMPSON and lonnn'r D. SIMPSON, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Pastors for Wrappers, die., of which the following is a specification.

This invention relates to that class of pastors for newspaper and other wrappers wherein a paste-holding'trough rests directly against the upper one of a 'pile of wrappers in such manner that paste can flow through the bottom of the trough onto the wrapper, and a newspaper or other article can be wrapped in the wrapper and the latter be folded and then withdrawn and the pasted edge secured, the paste-trou gh then falling or comin g directly against the next wrapper, and so on throughout the pile. This class of devices as heretofore constructed objectionable because the trough cannot be practicably and successfully applied to wrappers of varying width to uniformly and properlyapply the paste to the wrappers.

The chief object of our invention is to iinprove pastel-s of fthe class referred to and providenovel, simple, eilicient, economical, and easily adjusted devices for dainlning the paste-trough to vary its' length, or, in 'other Words, to confine the paste without possibility of-leakage within a certain part of the length of the trough, which length is variable at -will for the purpose of adapting the trough to wrappers which dier or vary in width.

The inventi( n also has for its object to provide a novel device for. lifting the"paste' troughand preventing the escape of paste during the time a fresh su pply or pile of wrappers is being placed in position.

y To accomplish these objects, our invention consists in the features of. construction and in the combination or arrangement of parts hereinafter described and claimed, reference being made te the accompanying drawings,

Fig. 7 is a bottom plan View of a portion of Fig, S is a detail. perspective View of one of the rubber dams,'and Fig. Qis a detail perspective View of one of the clamp-yokes for wedging and holding the rubber dams in the paste-trough.

In order to enable those skilled in the art describe the saine in detail, referring to the drawings, in which the numeral 3 indicates a material suitable for the purpose, but preferably inthe form of a square block. This base board or plate is provided with two perpendicular posts 4, located near its edges and extending through guide eyes or orifices 5 at ably made as a single casting of sufficient Weight for the purposein hand. The side Walls of the trough diverge from the bottoni Wall, and at their upper edges are provided with lateral iianges 7. The bottom wall of the trough-is constructed throughout its arranged perforations S and with transverse .grooves 9,wl1icl1 intersect these perforations.

grouped somewhat closelyV together, as will be 'clearly understood by reference to Fig. 7, and the construction is such that the paste passing through the perforations will iiow into the lgroov'es'aud thus be more uniformly distributed u'pon the wrappers than in those prior 'paste-troughs where the lpcrforations are actually closed at their lower ends bythe Wrapper itself Awhen the trough rests thereupon.- l

The trough is approximately V-shz'tped in cross-section, and into it are fitted two dams 10,'each composed of a soft-rubber block approximately triangular in shape and adapted to accurately iit the innersurfaces of the sides and bottom wall of the trough, as best seen -in Figs. 2 and 5. 'lhese soft-rubber dannningblocks are adjustable toward and from each tional view showing the lifter in position on to nahe and use our` invention, we will now base board or plate of any construction and` The transverse grooves and perforations arel ythe ends of a paste-trough L, which is prefervlength with a large number of alternately- IOO '- v.thatythe clamp-yokes 12'canfbe caused" to act-- other in the trough to vary its length, or, in

other words, to coniiuethe paste within a cer- .tain part ofthelength of the trough, which length can be increased or diminished at will, thereby enabling one trough to be practically used for applying paste to wrappers which differ or vary more or less in width. The upper edges of the damming-blocks are convex or curved and normally project slightly above the upper edge of the trough in such manner justed to any required position, according to the adjustment of the dams which may be necessary to adapt the trough to the width of wrappers being used. The pile of wrappers is placed upon the base board or plateto rest at one edge squarely against an adjustable gage or back-stop '14, arranged in rear of the trough. The side edges of the pile of wrapv pers have a bearing /againstadi ustahle :side ,l

The gages v111 and 1'5 nay be gages 'or stops 15'. adjusted in any suitablemanner; but as here shown they are provided with slotted basepieces having slots through which screws are passed, as usual. rectly' against the uppermost wrapper, as clearly shown in Fig. 2, which figure indicates a newspaper or other article being wrapped up i u the uppermost wrap'per. I When the newspaper or other article is partially wrapped up, as indicated in Fig. 2, the attendant places a finger or hand upon the pile of Wrappers infront of the articles being wrapped up and then withdraws the uppermost wrapper fronibeneath the paste-trough, whereupon the latter will instantly descend and rest against the next wrapper, and so on throughout" the pile. The paste in the trough flows through the perforations 8 and is distributed into the transverse grooves 9, so that the paste is applied uniformly tothe wrapper, andby reason 'ofv the grooves intersecting the perforations thej-bot'tem'of the paste-trough will -not unduly scrape off or remove the paste from the wrapper when the latter is withdrawn from beneath the trough. This is a desirable and important feature in that the depositing of the paste in spots is avoided and" the proper quantity of paste is left upon each wrapper, so that it can be properly and se-v curely sealed.

trough, it is necessary to lift the latter, and obviously it is desirable to' prevent the out- The paste-trough rests di.

flow of paste during the time that the pile or supply vof wrappers is being placedin position. We therefore provide the novel device illustrated in Figs. 4 and '5, which serves as a .handle to lift the trough and as a means for closing the perforated bottomof the saine.

This device is composed of a sheet-metal plate 16, having its upper edge portion rolled or turned into a more or less elastic rim 17, and

its lower edge is bent laterally to provide a fhorizontalharige '18; of a length coextensive with the lengthofffthe trough and preferably of a width greater than the width of the bottom of the trough. The flange 18 is adapted to be inserted under the trough and the rolled- .or turn ed rim 17 can then be pressed into engagement with the inside of the trough near its upper edge, as clearly shown in Fig. 5.' The trough can then be lifted by grasping the rolled or turned rim 17 in the fingers, so that a fresh pile or supply of wrappers can be placed in. proper position under the trough, and during this time the outiiow of the paste through the perforated bottom is eectually prevented by the flange 18.

Ourinvention provides a characteristic and novel paster which is susceptible of general and practicable application in connection with wrappers of any width within the capacity of the full length of the trough. j The trough can be used in connection with wrappersthatyary in width .bysmplyndjustiug 4the dams to meet the conditions required,'and there is no possibility of leakage, such as will occur where it is attempted to employ horizontal slides in thebottom of a trough to ad apt it to wrappers of varying width.

In adjusting the rubber dams the adjustment should be such that they will cover about one-eighth of an inch of the wrapper at each side, or, in other words, it is advisable to lso adjust `the dams that the distance between,

the same will be about one-fourth of an inch blocks for wedging them in the trough and holding the same in any position to whichv adj usted, substantially as described. i When a fresh pile or supply of wrappers isy to be placed in position under the paste-I 2.
